7	Use this skill when:
8	- Implementing GitOps workflows for Kubernetes
9	- Automating deployments from Git repositories
10	- Managing multiple environments declaratively
11	- Implementing progressive delivery strategies
12	- Synchronizing cluster state with Git
13
14	## Prerequisites
15
16	- Kubernetes cluster with ArgoCD installed
17	- kubectl configured
18	- Git repository for manifests
19	- ArgoCD CLI (optional)

21	## Installation
22
23	```bash
24	# Create namespace
25	kubectl create namespace argocd
26
27	# Install ArgoCD
28	kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml
29
30	# Get admin password
31	kubectl -n argocd get secret argocd-initial-admin-secret \
32	-o jsonpath="{.data.password}" \| base64 -d
33
34	# Port forward to access UI
35	kubectl port-forward svc/argocd-server -n argocd 8080:443
36
37	# Login with CLI
38	argocd login localhost:8080
